如何确定每根吊杆索力调整量,如何确保索力调整后与目标索力误差最小在拱桥吊杆索力调整中需要解决的问题。结合成渝高速内江新龙坳提篮拱桥的吊杆更换工程,介绍影响矩阵法在拱桥吊杆索力调整中的应用。该方法在实际工程的应用中取得良好效果,可为同类工程提供参考。
How to Determine the Adjustment Amount of Cable Force of Each Suspension Rod and How to Ensure the Minimum Error of the Tension with the Target after Adjustment of the Tension Force. In combination with the replacement of the boom of Xinlongpo basket-pull arch bridge in Neijiang-Chongqing Expressway, the application of influence matrix method in adjusting the cable force of the boom of the arch bridge is introduced. The method has achieved good results in the practical application of the project, which can provide reference for similar projects.
